These are good theories, but I would tend to refute them in both cases. First of all I now know that the system is behaving in exactly the same way for the old and the new memory. About an hour into a backup today I got a spontaneous reboot. This is with the original memory. In most logs I can see this reboot happening at 14:36:18 today. I see nothing in any log in the time immediately before this to indicate a problem. I've checked messages, syslog, kern.log, dmesg, and daemon.log... I see nothing just before that.
I will do the load test however and tell you how it goes.. I can get a multimeter. \ Pedro M. S.
